Specification of Letters Patent. Application filed August 9, 1912.Serial No. 714,264.

Patented Mar. 31, 1914.

To all whom it may concern: 1

Be it known that we, PETER F. WHITE citizens of the United at McNeilIsland, in the State of Washington, have new and useful Improve- States,residing county of Pierce, invented certain ments in Tooth-Brushes; andwe do hereby declare the following to be a full, clear, and exactdescription of the invention, sue as will enable others skilled in theart to which it appertains to make and use the same.

This invention has special reference to tooth brushes and moreparticularly to an improved sanitary tooth brush which embraces a handleforming tool and a separable brush and head capable of being inclosedtherein when not in use so as to maintain the brush in a clean andsanitary condition.

Another and important object of the invention consists in theprovisionof a handle member of novel formation having a guideway retaining thebrush member in a closed position whereby the same may be securely heldwhen in use or not in use and which also renders the device verydesirable in use when traveling inasmuch as the same can be I carried inthe pocket or'packed in a suitcase or valise without'soiling theclothes.

I body,

With the above and other objects in view, the invention consists ofcertain combina tions and arrangements of parts as will be herein-aftermore fully and illustrated in the accompanying ings, in which:

Figure 1 is a side 'elevation'of our improved tooth brush when not inuse. Fig. 2 is a similar view but showing the brush as in use. Fig. 8 isa longitudinal sectional view of the device shown in Fig. 2. Fig. 4 is asimilar view of the device as shown in Fig. 1. Fig. 5 is a crosssectional View taken on the line 5-5 of Fig. 1'. Fig. 6 is drawa detailperspective view of the brush ele-' ment removed.

As illustrated, our improved tooth brush embodies a handle 10 in theform of a hollow tube having a longitudinal slot-11 in its such slotterminating short of the end portions of the tube. One "end of the tubeis closed by an end wall'lQ. while the other end is open. The side wallof the tube adjacent each of the ends is thickened is clearly shown inthe drawing. The side edges of the. slot' 11 form a pair of'fiangedsides or ribs 13 and in continuation of the copies'ot this patent'may beobtained for the brush element described, claimed vantages over andgerms,

handle having five cents each, by addressing the ribs 13 are internalribs 14 at the forward end of the handle for receiving-l and. holdingtherein. T is latter element is indicated by the numeral 15 andcomprises a stem formed at its free edge with an enlargement 16 ofsubstantially circular or oval cross section and conforming to theinterior cross section of the tube forming the handle while the oppositelongitudinal side edges of the stem are formed with grooves or guideways17 for engage: ment with the ribs 13 and 14 of the handle members so as.to hold the brush element and head 18 securely in engagement with thehandle. The enlargement 16 is preferably made to fit snugly within theenlarged open end of the handle so that the brush may be readily engagedin the handle when not in use or when desired to use the brush, so thataccidental displacement of the brush element is prevented. It will alsobe observed that the back portion of the handle is reduced in thicknessadjacent to the head to rovide a gripping portion, the curvature ofwhich may be varied.

The parts are preferably constructed of hard rubber although the samemay be con structed of bone or other desired material, as falls withinthe scope claimed.

It will thus be evident that the device can be economically produced andit will be further apparent that the device has many adview of the factthat when not in use, be inclosed and thereby not thus insuring o thesame being kept absolutely clean and sanitary.

We claim:

A tooth brush comprising a tubular a slot extending longitudinallythereof, a brush carrying element having grooved sides engaged by theedges of saidslot and slidablewith reference to the handle, and a headon said brush carrying element adapted to close the end of sai handlewhen positioned therein. v In testimony whereof, we aiiix our signaturesin presence of two witnesses.
